Congruent Triangle Proofs

Front

What does CPCTC stand for?

Back

Corresponding Parts of Congruent Triangles are Congruent

Front

What is the ASA congruence criterion?

Back

If two angles and the included side of one triangle are equal to two angles and the included side of another triangle, the triangles are congruent.

Front

What is the AAS congruence criterion?

Back

If two angles and a non-included side of one triangle are equal to two angles and a corresponding non-included side of another triangle, the triangles are congruent.

Front

What is the SAS congruence criterion?

Back

If two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.

Front

What is the SSS congruence criterion?

Back

If three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.

Front

What is the definition of congruent triangles?

Back

Triangles that have the same size and shape, meaning their corresponding sides and angles are equal.

Front

What is the Reflexive Property in triangle congruence?

Back

Front

What is the Midpoint Theorem?

Back

If a point is the midpoint of a segment, then it divides the segment into two equal parts.

Front

What is the significance of vertical angles in triangle congruence?

Back

Vertical angles are always congruent, which can be used as a reason in triangle proofs.

Front

What is the Alternate Interior Angles Theorem?

Back

When two parallel lines are cut by a transversal, the alternate interior angles are congruent.
